## Description

The Cooper Discoverer AT3 XLT All-Season LT285/70R17 121S E Tire is designed for lifted, leveled and extra-large pickups for extreme hauling and aggressive off-roading, with a side wall design that makes this the industry’s best looking AT tire.

This ultra-capable tire offers the tread durability to handle backroad travel and weekend off-roading with the quiet performance for weekday driving around town.

Review: Most well-rounded tire I can find! - I have less than 1k miles on these tires at this point, wanting to get a quick review out there to help any buyers interested in this newer release! I had difficulty finding reviews on these. These tires are extremely similar to the standard AT/3, which is an already excellent tire. The additional features on the sidewall both look good and should perform better for off-road durability, which was never really an issue. On the road, these tires are almost silent when new, and ride very smoothly and seemingly efficiently. I would recommend them as one of the better tires for this price point! UPDATE*** I just completed a 5,000 mile tire rotation with my tires. I added a photo after wheeling the Daniel Boone Backcountry Byway. To this point, the tires are wearing very smoothly, riding quietly, holding their balance, and very capable off-road. I have had one puncture from a screw that was easily fixed with a tire plug. I still highly recommend these tires! UPDATE*** 10,000 mile rotation is great. Haven’t been balanced since initial installation, and have been off-road on multiple occasions. Still silent on road, smooth, with VERY minimal signs of wear! Buy them!
Review: Fantastic tire!! My new favorite. - Great tire! 4000 miles on them and still as quiet as they were when new. I mounted them myself and planned to get them balanced at a local shop. To this day they've never been balanced and are vibration free all the way to 70+. I'll keep buying them as long as Cooper keeps making them.

## Questions & Answers

**Q: Do these tires have the white lettering like the photos show?**
A: Hello,
According to the manufacturer part number, these tires do come with the white lettering on the sidewall. Hope this helps!
Thank you,
Tires-easy.com

**Q: Are they blackwall or white outlined?**
A: Hello,

These specific tires actually come with a black sidewall, so it does not have the raised white lettering. This information is located on the description of the tire, (for future references). BSW is for Black Sidewall, WSW for White Sidewall, and WL for White Lettering. 

Hope this helps!

Thank you

**Q: Does the 285 65 r20 come with raised white letters? i noticed it says blk next to them.**
A: Hi! You can select the 285/65R20 size with either a black sidewall or raised white lettering. Just select the option you'd prefer in the drop down! Thank you!

**Q: Anyone know how well these do in snow? My 2010 ram sucks with the current tires im looking for a good winter tire**
A: I have a 2014 Ram 2500 with these tires. This is my first winter driving with these tires and for the first time I am able to drive good in the snow without being in 4wd. Of course in deeper snow I drive in 4wd, but can go regular speed with no issues.

### ⭐⭐⭐⭐⭐ Fantastic tire!! My new favorite.

### ⭐⭐⭐⭐⭐ Exceeds expectations so far.
*by G***F on May 15, 2021*

I've only put a couple hundred miles on them so far, but I put them through mud, gravel, wet grass, and a stream crossing and they handled admirably. They're easily the quietest AT tire I've had, virtually silent even at 80 mph. I'm really impressed by the manners on pavement, very grippy through takeoffs and in the curves. They felt a touch floaty on gravel, but nothing serious. Not as good as a dedicated mud tire in the muck, but I would class it as very good to excellent for an All Terrain tire. On wet grass it did extremely well, not aggressive enough to mess up the clients yard, but grippy enough to go slow without spinning out, same with the slick rock in the creek. I'm interested to see how these puppies do in the snow and ice this winter, but based on reviews and my experience so far I expect it will be good to excellent. Looks were secondary to my decision, but I have to admit they're a tough looking tire, at first glance you could easily think they were a dedicated off road tire and being an old fart with a white truck I like the way the raised white letters look too although I know that's not the thing anymore (don't worry you can put the all black side out if you prefer).
